Topic: Toyota hydro assist bleeding problem

[MR_DIY]

cameron and I gravity bled the system and then cycled it both running and OFF about 200 times.  when it stopped producing bubbles at the resv'r we set the truck down on the ground and tried to turn.... IT was like manual steering, I couldn't even turn it.

help!?

did you make sure you got all of the shaving out of the vein on the box when you tapped it?  mine was packed full of small shaving when i did mine.

are the hoses connected properly to the ram and box..if they are switched it will try to fight itself. When u say gravity bled do you mean u unhooked the ram from the mounts and let it hang down as the lowest part of the system?

[DTB]

not sure if this might help too>> u probably already have this info....Before Bleeding - Check and Correct as Needed:
· Inspect steering system
· Hoses must not touch any other part of the vehicle
· Steering system noise could be caused by hose touching frame, body or engine
· All hose connections must be tight
· Loose connections might not leak but could allow air into the system

How To Bleed:
1. Switch ignition off
2. Raise front wheels off the ground and secure vehicle with jack stands
3. Turn steering wheel full left
4. Fill fluid reservoir to "FULL COLD" level, leave cap off
5. Turn steering wheel lock-to-lock at least 20 times. On systems with long lines or ram assist
cycle steering at least 40 times.
6. Trapped air may cause fluid to overflow - keep fluid level at "FULL COLD"
7. Start engine and maintain fluid level at "FULL COLD"
8. Reinstall Fluid Cap
9. Keep Engine Running for 2 minutes
10. Return wheels to center and lower wheels to ground
11. Turn wheel with engine running

Verify the Following:
· Smooth power assist
· Noiseless operation
· Proper fluid level
· No system leaks
· Proper fluid condition (no bubbles, foam or discoloration)



another version of the same>> Drain old fluid from steering fluid reservoir and lines. Connect factory lines to and from steering box and reservoir. Fill reservoir with  steering fluid.

Using a floor jack, lift the front of the truck off the ground. With the engine off, turn the steering wheel from lock to lock 20 times. Check and fill steering fluid reservoir as needed. Start truck and allow to idle. Turn steering wheel another 20 times from lock to lock while keeping an eye on the fluid reservoir. Top off as necessary but do not overfill. If ram hoses are connected backwards, the steering box and ram will fight each other and you will not be able to control the position of the wheels. If you feel major binding in the steering check to see that the hoses are connected correctly.

Lower vehicle to the ground. Check and maintain fluid level as needed.

thank you all.

dtb- I'll try this way to make sure I'm not doing this wrong. thanks

all others... the box was professionally done and I'm sure that it is right (good suggestion though).  I have the hoses connected as the illustration on trail gears site shows so they must be right (will double check it though b/c I suspected this also).

I'll post back with what I find

about 11:30pm last night cameron and I took the pump apart.  it is not pumping.  I guess I need a new pump in the  next 3 days.  that sucks.  my pump must have been on the way out and the extra work I asked it to do was too much.

I am glad that I now know what it is so I can fix it. I'll start searching for one now both aftermarket, parts store and junkyard (if I have to)

If your going to replace the pump i would go with a TC pump for PSC motorsports. There a little pricey but well worth the extra cash for 300 psi and 4 gpm flow rate more then the stock pump. Just my two cents.


Trail Gear also sells a tc pump now with all the brackets and pulleys and belts you need for a good price but its Trail Gear and well.............................................I am not a big fan of theirs

Good luck

thanks man.

I'm waiting to hear from psc b/c I want to run their pump b/c it'll be cheaper than the trail gear setup.  if not then I'll run TG's. 

also talking to rockrat at rock4xfab.com

update tomorrow
